I don't know for certain, But I'm pretty sure you can't.  The reasons I think that are:
1.  The moon is orbiting around us as we spin on our axis, the sun is staying in the same place RELATIVE TO OUR SOLAR SYSTEM.
2.  The moon deviates within about 10* up and down in it's orbit around us.

Wouldn't it be easier to just find the north star?

Despite its motion relative to the Earth, the Moon rises and sets at roughly the same interval as the Sun. So the watch thing might work. But it may rise during the day, or have set by sundown... not much use in using the moon when ol' Sol is visible. 
And on nights when the moon is in its "new" phase, it may not be visible at all, unless there's some earth-glow reflecting off it.

Regardless, if you know what hemisphere you're in and have the time to watch the Moon for a bit to see which way it's "going", you can easily work out the cardinal directions. Just like the Sun, it rises in the east, sets in the west, and is seen in the southern sky from the northern hemisphere and in the northern sky from the southern hemisphere.
And when there's no Moon present, there are these really cool blinky lights in the sky called stars. Most of them rise in the east and set in the west...but if you don't have time to wait for stars tio crawl across the sky, the exceptions to the rise east/set west rule are very convenient. For example, if you can find  Polaris (from the northern hemisphere, you have true north. How to find it? It's the one that doesn't move all night long (because it's oriented roughly over the Earth's axis of rotation). all of the other stars will appear to circle around it.

But I forgot- we don't have time to watch the stars move, and note the ones that do not. Okay, then- find the Big Dipper, and trace a line up from its bowl. That really bright star there is Polaris (aka Alpha Ursae Minoris, a supergiant about 434 light-years away).  It's never directly overhead unless you're at the North Pole, so whatever side of the sky it seems to be on if you look straight up is true north. The rest is easy enough to figure out. 

just saying but if you have a  watch and you can see the moon,why dont you check the time and see where the moon is?
if its midnight,well,then you might have a problem.

Club. It's in the middle of the night. You aren't just gonna get out and ask for directions. Maybe thieves, Murderers e.t.c are out there

Just to clarify

When I was out on back roads at night, before the days of GPS, cloud cover could be plus. I could see city lights reflecting off the bottom of the clouds from 40 miles away. Although that doesn't tell you what direction your going it does usually get you back to a main road.
